It IS a limited time joke. It only lasted a few episodes- maybe half of the first season or so- on 3rd Rock. But things like experiencing your first sneeze (as Sally did)- or in Marvel Comics' Beyonder stories, the aftermath of consuming food for the first time and having the proper use of the facilities explained happened in only a few panels- can help establish the alienness of the PC.
The more serious side of this is would include not necessarily understanding what pain is, why you are thirsty, why a fever is bad...things we've all experienced for decades and instantly understand and react appropriately and nearly instantly to could still be new experiences for this PC...meaning he simply forgets what is supposed to happen.
Playing this up to the fullest would require some forethought and partnership with the DM, so that if/when the PC simply forgets his new body needs sleep and he drives himself to collapse...
Over time, such incidents decrease in frequency, but are never completely eliminated.
